Matt, If you have some test data imported or added into your SPINMap graph, you will see some information as you create mappings. After your SPINMap is finished, you can drop it.
For example, when you draw a line between classes and define the changeNamespace function, you should see right away examples of the URIs being created without having to run inferencing as a separate step. Check that they make sense. In this case, correspond to the URIs of the resources that are members of the Order class. As I understand it, in your data, the URIs of the items and orders will match as longer as you change the namespace. For example, you have www.example.org/items/x123 and correspondingly www.example.org/orders/x123, so that the only thing you need to do is replace www.example.org/items/ with www.example.org/products/. Correct? If this is not true, you need to have a different mapping function. Then, I am not sure that I understand what you mean by "I then drew a line from the Item class to a new property on the Order class, totalPrice, and set the function to equals, just to see if I can get the property to show up". I would think you need to draw a line from the unitPrice property in the Item to the new totalPrice property in the Order.

You will understand that it is quite difficult and time consuming to reproduce exactly the same scenario that you had. In principle I see no problems with your proposed solution, although SPINMap does have its limits and sometimes it is indeed faster to just rely on SPARQL CONSTRUCT rules to do the work.
